The girls Shot a whole 300 round box of federal automatch today. Lots of light strikes and some nasty failures to feed where the round noses up into the top of the slide and the rim gets caught under the front mag lips. This gun is pissing me off.

Haven’t figured out shims yet

Also: anyone have a preferred tiny-profile Red dot optic? I have a couple RMRs but they're too big and heavy for this thing. I understand the SIG Romeo zero is a frontrunner for use on this pistol, and I'm aware of the Shield RMSc and RMSx, but which others in this category should I be looking at?

I have a Holosun 507K X2 on one and it is pretty small and alot of fun. Have the Sig Romeo zero elite on another and it is ok as well except the function button is hard to get to and a little bit of a pain to operate.

Thanks. So you have no reliability issues with the 507K on the P322 despite the optic’s heavier weight?

No issues . Sorry you are having a few problems. Most of the time I don’t cram the full 20 rds into the Magazine. I just put between 15-17 rds and try and make sure the magazine is loaded correctly and it functions pretty good. Good Luck

Mine has a 507k. Any issues I have had appear to be magazine related not slide weight related.

Thanks. Hopefully the three new mags I have work better. I’ve marked the one that has had feeding issues. It sucks that we have to pay $.10/rd for reliable .22 ammo these days. I can almost reload 9mm for that.

It takes some care loading the mags, I have learned to not lose spring pressure while loading and once loaded make sure none are pointing down.
If a rim gets behind the next rim, you will have a FTF

Here’s a video overview including some possibly tedious ammo reliability testing.

Short answer: lots of light strikes with Aguila super extra plated and LRN, light strikes and feeding issues with Federal automatch, couple feeding failures with CCI Mini-Mag, no issues IIRC with Remington SV from CMP, feeding issues and jams with Winchester 333 bulk. Winchester 36 grain varmint ran one mag I think, new federal champion feeding issues for first couple of mags but last two mags, approaching 500 rounds through the gun, no issues. So it’s a mixed bag for sure. I’m going to shim the mainspring I think.

Anyone find a cure for the live round stovepipe? I have been having the same issue using CCi CPRN 1200fps rounds and some others. It didn't happen at first but now more frequently. I contacted Sig support but haven't heard back yet.

I tried mine out again last week and it still doesn't work reliably. I guess the elves didn't fix it. I haven't tried to shim it yet. Bothered by it so I'm ignoring the gun for now.

Aguila ammo is a no go for me. My 322 has issues with it as well. I only fire copper platted ammo and prefer to only shoot CCI Mini Mags. I will confess that I installed an Armory Craft trigger in mine. My daughter has gotten some light primer strikes and stove pipes, but I chalked it up to the Aguila ammo. I’ve had good luck so far with the Romeo Zero that came with it. This thread is making me want to get it out and shoot, my daughter loves it!

I have a holosun 407K X2 on mine..tried many different kinds of ammo but my particular gun runs best on CCI SV and or CCI mini mags..most others FTF issues

LIVE ROUND STOVE PIPE CURE: Take the mag apart, clean it good, while disassembled spay everything , follower, pin, inside of mag, and spring with CRC heavy duty silicon or similar. Blow dry the silicon spray with compressed air and reassemble the mag. Load it correctly. Reasoning for the above: Have 6 mags, 20 and 25s, 1 of the 20s is new, one of the 25s is new, all the rest hav been cleaned and lubed and used with never a stove pipe. Ammo is CCI Mini mag copper plated. All mags were loaded at home and verified correct. At the range the 2 NEW mags that were not lubed produced unfired stove pipes. The lubed mags were reloaded at the range and ran pefrect. Try it, would like to know if this works for others.

I have to say the Aguila .22lr is garbage. I ran about 400 rounds of it on Sat. I had at least 10 misfires. The same thing happened the last time I ran them through my P322. Typically I will get 2-3 misfires on 400 rounds of CCI or Federal. For .22lr this seems ok. It’s simply a dirty round.

Aguila Interceptor seems a bit problematic for my P322 (my S&W 15-22 loves that stuff).

Federal 'Champion' 36 grain (cheap pricing, $0.06) regular velocity runs, well, like a champ, in my P322.

Clean it, load it nicely, and use typical velocity cheap ammo...a good recipe.

22lr is my favorite of all - have several Volquartsen and Hammerli pistols, still, this little P322 is my hands-down favorite range gun.

I just bought 3 new oem magazines for mine. They are the 25 round ones. The first day was not good. Lots of misfires. I hope it was the Aguila rounds as they just don’t like this gun. Only one misfire with the original magazines and 14 with the new mags. Is this normal with the 25 round magazines?

I had stove pipe issue with new mags 20 and 25 which I had not lubed with silicon spray. The 25s are VERY particular about how they are loaded, one at a time push in, nose up.. and the mags need to be lubed with silicone to run perfectly.. I disassemble them after every use, clean any carbon out of the top of them, spray with CRC heavy duty silicone and blow dry with compressed air.. no loading issue.. now if you are talking lite strikes that did not actually fire.. probably not the mag.
